The main business of Bandai Namco Holdings consists of the design and implementation of management strategies for the conglomerate and providing support for the overall business of its subsidiaries. It brings all of the brands of Namco and Bandai into one organized brand, and is subsidized into things like the separate companies (Namco and Bandai) or others like Bandai Namco Entertainment, the video game division of the company, as Namco now does things lie manage the countless tourist and amusement attractions they have across the world, like Namco Funscape in London or their game rooms in the Mall of America. They also supply various arcade machines to movie theatres and arcades across the globe.[3]

Namco Bandai Holdings was created in 2005, when Namco and Bandai performed a management integration,[5] 57% percent of the company's holding went to Bandai while 43% went to Namco. Furthermore, Bandai swapped one of its shares for 1.5 of the new Namco Bandai. Namco traded evenly with a one-for-one share.[6] carried out via a share exchange. The shareholders of Namco received one NBHD share for each Namco share and the shareholders of Bandai received 1.5 NBHD shares for each Bandai share.[2] Prior to the merger, lots of organization of the two companies took place, as subsidiaries of Bandai or Namco were now subsidiaries of other Bandai or Namco companies that better suited what the company was doing.

In September 2006, BNHD acquired CCP Co., Ltd. from Casio and made it a wholly owned subsidiary.[7][8]

NBHD fully acquired developers Banpresto (whose video game operations were absorbed into Namco Bandai Games on April 1, 2008)[9] and Namco Tales Studio since the merger. Formerly, both were partially owned by Bandai and Namco respectively. On March 31, 2006, Namco and Bandai's video game operations merged into Namco Bandai Games Inc. (NBGI). Namco's arcade and facility management continues under the name of Namco Ltd.

The business of Bandai Networks Co., Ltd. was merged into Namco Bandai Games, Inc. in April 2009 and Bandai Networks subsequently ceased to exist as a separate company.[10]

Namco Bandai bought a 34% stake in Atari Europe on May 14, 2009, paving the way for its acquisition from Infogrames.[11] Until June 30, 2012, Infogrames had the option to sell the other 66% in Atari Europe to NBHD.[12] Between June 31, 2012 to June 20, 2013, Namco Bandai gained the option to acquire the 66% stake.[13] On the 7th of July 2009, Namco Bandai Holdings bought 100% of Atari Australia Pty Ltd. NBHD acquired 100% of the shares of Atari Asia Holdings Pty. Ltd. and 100% of the shares of Atari UK Ltd.[14] These former Atari companies were merged into Namco Bandai Partners to handle distribution and publishing support in PAL territories, including contracts for other publishers' titles. Namco Bandai has also pursued whole ownership of D3 Publisher, owning 95% of the company. Right now, D3 makes tie-in titles, such as a series of Adventure Time, Ben 10, and a Marvelmobile game called Marvel Puzzle Quest.[15]

Namco Bandai has also created many things since the merger of the company, such as the new Pac-Man animated TV show, Pac-Man and the Ghostly Adventures, and the ShiftyLook webcomic series, which focuses on reviving Namco's classic game series as comic strips. Comic strip series include Bravoman, Sky Kid, Xevious, Alien Confidential, Rocket Fox, Scar (based on Genpei Toumaden), and many more.

In August 2013, Namco Bandai opened a studio in Vancouver, broadening its reach for the western demographic.[16]

The organization of BNHD has changed considerably since the merger. In 2007, NBHD consisted of 5 SBUs (strategic business unit) and the Affiliated Business Companies.[18] In April 2009, the Game Contents SBU and the Network SBU were merged[19] and since April 2010, NBHD consists of three SBUs and the Affiliated Business Companies.[20]

The Content SBU is responsible for all video game products, including games for home consoles, arcades, and mobile platforms,[23] as well as anime production and distribution. The bulk of these facilities are made up by the former Namco, also with Banpresto and D3 Publisher, and the Sunrise anime production company, along with the following:
